Overview

• Anses, France's health agency, has raised concerns over pyrethrinoid insecticides, urging rationalized use and stronger biosurveillance.
• Scientific studies link prenatal exposure to behavioral disorders in children and general exposure to fertility issues and cancer risks.
• Deltamethrin, a commonly used pyrethrinoid, is associated with increased risks of leukemia and lymphoma in occupational settings.
• Pyrethrinoids are prevalent in agriculture, household insecticides, and veterinary products, complicating exposure assessments.
• Anses has formally requested EFSA to re-evaluate deltamethrin by August 2026 and tefluthrin by May 2027 to address health concerns.
